Mestre de camp or Maître de camp (, camp-master) was a military rank in the Ancien Régime of France, equivalent to colonel. A mestre de camp commanded a regiment and was under the authority of a Colonel General, who commanded all the regiments in one "arme". The rank also existed in Portugal and Spain, as mestre de campo. The rank of mestre de camp was demonstrated by wearing a pair of épaulettes with gilded or silver fringes. The rank was abolished at the Revolution and replaced by that of chef de brigade.
